I just had a baby on September 15th and had to have an emergency c-section, which they filled me with so much drugs in my epidural that my hands and also my head were numb as well. I went to the emergency room yesterday b/c I have been recently put on a lot of new medications, that are for my UTI , lexapro for my depression, a mood stabilizer depacoat, and Klophon for anxiety plus I have been taking Suboxone for 1 1/2 or 2 years, I was falling asleep when in active even when just standing up. It was scary well they took my blood and urine sample and it came back in my urine that I had cocaine in it and i have never touched the stuff. What could cause this? My mom was with me and now thinks I am a drug addict and it breaks my heart. I really need help. Could I have been from the epidural??

I need help as quickly as possible so I can either showw my mom that see it was not me or look for another way that it could have been a false positive, b/c there is no way I should of had that in my system. I do not do drugs. I have two children and they could get taken away from me over something I did not even do.

Yes, Lidocaine is actually related to Cocaine and it has been known to cause false positives for it, in people that are using it regularly.


Learn more Lidocaine details here.

There are also other medications that may cause it. What else do you take?

I had some pretty serious dental work done the day before an appointment with my pain Doctor. Since he prescribes pain meds for me monthly, I am usually asked to UA as I was this time. I have been surfing your website and now am concerned that the lidocaine I was given could cause me to test positive for cocaine. Is that possible and if it is, what should I do?

Jeremy, you are misinformed re methadone it is a great pain reliever for people who cannot afford OxyContin. I am not an addict however I have Degenerated Disc Disease and methadone takes away my pain. It does not make me feel high like OxyContin can.

Andy, I have had to take iOxycontin 80 6xs a day plus 6 30 mg oxycodone for severe Degenerative Disc Disease. Obviously, you have never experienced our pain. Thus you need to keep your ideas to your self. I can now get out of bed, hold my children and play them. If that is wrong?

Honey, I came up positive for cocaine from a root canal and crown. The company swears that the tests know the difference but they don't. UA can not differentiate from one caine to the next. Cocaine, Lidocaine, Novocaine. etc. the idiots running this country have turned a blind eye to drug traffickers from other countries. Instead we hunt down honest patients who are playing by the rules. Contracts with our doctors so we can be persecuted. The reason the drug epidemic is so big in the US? They've made it so hard to play by the rules, one is forced to go to the streets. If I was being threatened about my kids, I'd DEMAND they test my hair to prove I was not doing drugs. This test is pricey but more accurate than urine and goes back further in time. What price do you put on keeping your kids? It's insane.

An ER drug screen has my friend as positive for cocaine and amphetamines. He doesn't do either drug. He had Lidocaine injections two days before this 12 of them down his back and he used cream with Baclofen, Bupivacaine, Cyclobenzaprine, Diclofenac, Gabapentin, Ketamine and Lidocaine. He uses said cream from his neck to end of spine several times a day. The night before his ER visit he also laid in a tanning bed a couple of hours after applying the cream. Could any of this caused him to test positive for the cocaine and amphetamines? If you have any references for your answers please I would like them too.

Hi Falsely Accused,

There has to be a connection between lidocaine & cocaine because there are several people that this has happened to. I am not a drug user and rarely even drink alcohol but tested positive for cocaine in a hair drug test from my employer. So, to prove them wrong, I went to a different lab and paid for a hair drug test myself and it came up positive again. 3 months prior to the drug test I had been injected with lidocaine several times for a biopsy. I had also had a tooth pulled and developed 'dry socket' and they gave me petroleum based Xylocaine to keep putting in the dry socket until it began to heal. However, I was told by 3 different doctors that Lidocaine will not show up as cocaine because they are not related in any way. There has to be something that can be done about this. Too many (non drug user's) are losing jobs and reputations because of this. If you find out any thing that can help, please post it here. And I will do the same. Thank you!

Oc 80 6 times a day and perc 30 5 times a day?! You're lucky to be alive. Your doctor is dumb and shouldn't be prescribing medicine to people.

Yes it happens a lot after dental surgery and you could get something in writing from your dentist acknowledging the ingredients you were administered and their possible false/positive metabulites being related to a positive cocaine result. As protection or as evidence for your attorney if the future ruins your life as many others were in the year 2016.

Lidia

No absolutely nothing wrong with that at all however I question the medical efficiency of prescribing a total of 650 mg. of oxycodone per day. There are far more effective options without exceeding toxic levels of oxycodone . If you were to research the toxicity levels of said drug you may find some eye opening results.

Ps. Not to mention this is a false positive for lidocaine thread. NOT an OxyContin / oxycodone thread.

I've been on oxycodone for 7 yrs and I had a urinalysis that showed positive for coke. I have not used coke, but I'm on liquid lidocaine viscous. Would that interfere with your results?
